Abstract
In 55 normal subjects left ventricular diastolic filling patterns were assessed by pulsed Doppler echocardiography. The ratio of early to la te peak diastolic flow velocities (E/A) was significantly higher at re st (1.51 vs. 1.29; p < 0.05) as well as during the exercise stress tes t (1.22 vs. 1.00; p < 0.05) in the group of younger subjects in compar ison to older normals. Therefore the age-related changes on diastolic filling indices with a reduced early filling due to prolonged relaxati on and decreased distensibility were maintained by atrial compensation even during exercise.
